The mp3 file for this episode of the podcast was somehow corrupted before I uploaded it to the feeds last night.
This morning, I discovered that the stereo underscore and theme music track on the file was somehow duplicated and offset, resulting in a pronounced echo. I will try to fix it when I get home from work late today, but if the entire track has to be remixed, it may take a while. I will keep all of you posted on my progress in getting this issue fixed. Thanks.
